New York City doesn't sit in just one county. Instead, the entire city spans five distinct counties, with each county matching one of the city's famous boroughs. If you're filling out official paperwork, looking up court jurisdictions, or trying to understand local government, knowing how these boundaries overlap matters.
The short answer is that New York City contains five counties: New York County (Manhattan), Kings County (Brooklyn), Queens County (Queens), Bronx County (The Bronx), and Richmond County (Staten Island). Each borough operates as both a municipal division of the city and a county under New York State law.
Why NYC Is Divided Into Five Counties
The current layout dates back to January 1, 1898, when the municipal government consolidated multiple distinct cities, towns, and villages into the "City of Greater New York." Before that consolidation, Manhattan was its own city, Brooklyn was the fourth-largest city in the United States, and Queens and Staten Island consisted of scattered rural towns and independent settlements.
When consolidation happened, the state preserved the underlying county structures for judicial, administrative, and record-keeping purposes. Over the next two decades, boundaries shifted slightly—most notably when Bronx County split off from New York County in 1914 to become its own independent entity. Similar insight on this trend has been provided by BBC.
The Five NYC Counties and Their Boroughs
Every single inch of New York City belongs to one of these five county governments. Understanding the pairing helps prevent confusion when dealing with real estate deeds, court summonses, or mail delivery.
- Manhattan is New York County: Spanning 22.7 square miles, this small island and its surrounding waters share a name with the broader state, creating endless confusion for travelers. It also includes Marble Hill, a tiny neighborhood physically attached to the Bronx mainland that legally remains part of New York County.
- Brooklyn is Kings County: Named in honor of King Charles II of England, Kings County is the most populous borough and county in New York State.
- Queens is Queens County: Originally encompassing a much larger swath of Long Island, Queens shrank to its current boundaries in 1899 when eastern towns split off to form Nassau County. It remains the largest borough by land area.
- The Bronx is Bronx County: The northernmost part of the city was originally split between Westchester County and New York County before being unified and eventually established as its own separate county in 1914.
- Staten Island is Richmond County: Named after the Duke of Richmond, this island borough officially changed its municipal name from the Borough of Richmond to Staten Island in 1975, though the county name stayed Richmond.
How County Government Works Inside New York City
Because the city government absorbed most traditional county powers after 1898, New York City counties function differently than counties in rural or suburban areas. You won't find a traditional county board of commissioners or a county-level legislature running day-to-day municipal services here.
Instead, city agencies like the NYPD, the Department of Sanitation, and the Department of Transportation handle services citywide. However, the counties maintain distinct authority in specific legal and political arenas:
- District Attorneys: Each of the five counties elects its own District Attorney who prosecutes state crimes committed within that specific county's borders. For instance, the Manhattan District Attorney only has jurisdiction over New York County.
- Courts: The New York State Unified Court System organizes its trial courts around these five county boundaries.
- Property Records: Deeds, mortgages, and land records are filed and tracked separately through the Office of the City Register or county clerk offices within each specific county.
Common Mistakes and Misconceptions
People often stumble over New York's administrative geography because terms are used interchangeably.
One frequent error involves mailing addresses. You can write "Brooklyn, NY" on an envelope, and the postal service delivers it perfectly fine to Kings County because the United States Postal Service organizes delivery zones by neighborhood names rather than strict county lines.
Another mix-up involves thinking Westchester County or Nassau County are part of New York City. While commuters flood into Manhattan daily from Westchester, Long Island, and New Jersey, none of those external areas belong to NYC or its five core counties.

Frequently Asked Questions
Is Manhattan the same thing as New York County?
Yes. Geographically and legally, the Borough of Manhattan and New York County occupy the exact same footprint, aside from minor adjustments like the Marble Hill border.
Why is Brooklyn called Kings County?
When the area was settled under British colonial rule, it was named Kings County to honor King Charles II. When it incorporated into New York City later, locals kept the historic county name while using Brooklyn as the primary municipal identifier.
Does Staten Island have a different county name?
Yes. While the municipality is called the Borough of Staten Island, the corresponding county is named Richmond County.
Are there any other counties inside New York City?
No. Exactly five counties make up the entire geographic area of New York City. Any other county in the state—such as Westchester, Nassau, or Rockland—lies outside city limits.
